我们研究了二氧化氮（NO2）、臭氧（O-3）、空气动力学直径< 10 μ m的颗粒物（PM10）和二氧化硫（SO2）对参加辛辛那提、克利夫兰和哥伦布、OH医疗补助计划的5-34岁哮喘患者的影响（N = 5416）。我们的研究时间为夏季，即6月至8月，从1991年7月1日到1996年6月30日。我们对每个城市每天因哮喘急诊（艾德）就诊的人数以及控制时间趋势和最低温度的汇总数据进行泊松回归分析。我们发现，在克利夫兰，PM10每增加50 mug/m3，哮喘ED就诊的可能性增加12%[95%置信区间（CI）=0-27%]，在辛辛那提，SO2每增加50 mug/m3，哮喘ED就诊的可能性增加35%（95% CI = 9-21%）。当对所有三个城市的数据进行分析时，所有污染物增加都会增加艾德就诊的风险，特别是SO2每增加50 mug/m3增加12%（95% CI = 1-23%）。归因风险估计显示，克利夫兰的影响是辛辛那提或哥伦布的五倍。1991年至1996年期间，辛辛那提、克利夫兰和哥伦布的空气污染增加了参加医疗补助的哮喘患者的艾德就诊率。(C)2002 Elsevier Science（美国）。All rights reserved.
We examined the effects of nitrogen dioxide (NO2), ozone (O-3), particulate matter of < 10 mum aerodynamic diameter (PM10), and sulfur dioxide (SO2) on asthmatics ages 5-34 years enrolled in Medicaid in Cincinnati, Cleveland, and Columbus, OH (N = 5416). Our study period was for the summer months, June-August, from July 1, 1991 to June 30, 1996. We preformed Poisson regression analyses for the number of daily emergency department (ED) visits for asthma in each city and on the aggregate data controlling for time trends and minimum temperature. We found a 12% increased likelihood of an asthma ED visit per 50 mug/m(3) increase in PM 10 in Cleveland [95% confidence interval (CI)=0-27%] and a 35% increase per 50 mug/m(3) increase in SO2 in Cincinnati (95% CI = 9-21%). When data were analyzed for all three cities combined, the risk of an ED visit increased for all pollutant increases and specifically by 12% (95% CI = 1-23%) per 50 mug/m(3) increase in SO2. Attributable risk estimates show a five times greater impact on Cleveland over Cincinnati or Columbus. Between 1991 and 1996, air pollutants in Cincinnati, Cleveland, and Columbus increased ED visits for asthmatics enrolled in Medicaid. (C) 2002 Elsevier Science (USA). All rights reserved.
